CVE-2025-68968 is a high-severity Double Free (CWE-415) vulnerability in Huawei Harmonyos. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 0.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-2 requires identification, reporting, and correction of system flaws like this double free vulnerability through timely patching as detailed in Huawei support bulletins.
SI-16 implements controls to minimize the impact of memory-related flaws such as double frees, preventing unauthorized access and exploitation attempts.
SI-10 validates and sanitizes inputs to the multi-mode input module, reducing the likelihood of triggering the double free vulnerability via malformed local inputs.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Double-free memory corruption in local input module directly enables arbitrary code execution by low-privileged attacker, mapping to exploitation for privilege escalation.
NVD Description
Double free vulnerability in the multi-mode input module. Impact: Successful exploitation of this vulnerability may affect the input function.
Deeper analysisAI
CVE-2025-68968 is a double free vulnerability (CWE-415) in the multi-mode input module affecting Huawei consumer products. Published on 2026-01-14T03:15:51.740, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation may affect the input function.
A local attacker with low privileges can exploit this vulnerability with low complexity and no user interaction required. Exploitation could result in high impacts to confidentiality, integrity, and availability, potentially allowing arbitrary code execution or system compromise within the affected input function.
Huawei has published support bulletins addressing this issue, available at https://consumer.huawei.com/en/support/bulletin/2026/1// and https://consumer.huawei.com/en/support/bulletinlaptops/2026/1//, which likely detail patches or mitigation steps for affected consumer and laptop devices.
